Hello,
Generally an error of this nature will not be reimbursed. We advise caution when buying items to ensure that they are the correct item you are looking for. However, you can try to submit a ticket to the in-game CS platform to make an appeal for reimbur*t since you do already have the outfit in question. Here is the link.

Thanks and good luck!
